You can think of inodes as a file structure, or possibly a database of all the information on a server, other than file names themselves or the contents of actual files. What this database does is identify the owners of the files, their permissions and miscellaneous metadata. Essentially, every image, file, email, directory and symbolic link on your Linux server requires an inode.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_cPanel_recommends_for_allotments_of_inodes\"><\/span>What cPanel recommends for allotments of inodes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Inodes are allocated on cPanel, which recommends actually setting up more than the default allocation of inodes on your Linux server\u2019s partitions. Typically, an allocation of inodes is assigned when the file system of a server is created, and that usually accounts for 1% of total size.<\/p>\n<p>cPanel goes on to recommend if everything is installed on just one partition, that the base WHM &amp; cPanel requires at minimum one million inodes, plus at minimum fifty thousand inodes per cPanel account used for hosting.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_are_inodes_structured\"><\/span>How are inodes structured?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A table of inodes is located on a specific section of the server whereby an inode number can then index that. You can find a file\u2019s inode number by using the ls -i command. Files that are stored on the HDD can be tracked via inodes which store metadata that points to files, directories or objects. Of the 128 bytes used in each metadata entry, certain attributes are included such as the inode number, ACL, file size, number of blocks, file access time, owner, permissions, file deletion time and status flags, among others. What metadata does not include are the file names themselves.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_happens_when_the_inode_structure_is_full\"><\/span>What happens when the inode structure is full?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It is possible to fill an inode structure before the space on the hard drive is filled. Why? The inode structure is limited in size, so if the drive contains lots and lots of small files, each taking up 128 bytes of the inode structure, you won\u2019t be able to create more files on the disk. The workaround is simply to free up inode storage.<\/p>\n<h4><img decoding=\"async\" class=\"aligncenter wp-image-51 size-full\" src=\"https:\/\/www.prolimehost.com\/wp-content\/uploads\/sites\/4\/2014\/08\/unnamed-e1408122780935.jpg\" alt=\"ProlimeHost Cheap Linux Server Hosting\" width=\"400\" height=\"80\" srcset=\"https:\/\/www.prolimehost.com\/blogs\/wp-content\/uploads\/sites\/4\/2014\/08\/unnamed-e1408122780935.jpg 400w, https:\/\/www.prolimehost.com\/blogs\/wp-content\/uploads\/sites\/4\/2014\/08\/unnamed-e1408122780935-300x60.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/h4>\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"BROUGHT_TO_YOU_BY_PROLIMEHOST\"><\/span>BROUGHT TO YOU BY PROLIMEHOST<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>We\u2019ve been in the web hosting industry for over a decade, helping hundreds of clients succeed in what they do best and that\u2019s running their business.
